... Since the 1980s Tetranychus urticae Koch has dominated Australian cotton due to its ability to develop resistance. Here we give screening data for a range of chemicals tested against T. urticae including abamectin, bifenthrin, diafenthiuron, etoxazole and propargite and speculate why abamectin resistance emerged without warning. Abamectin resistance was not detected in T. urticae in Australian cot ...
... In the United States, the average field size has roughly doubled from the 1980s to the mid-2000s, while average cropland has stayed the same. This will likely influence how semi-natural habitats and edges affect local patterns and processes such as natural pest control or pest densities.We hypothesized that densities of two cotton pests, cotton fleahopper (Pseudatomoscelis seriatus) and verde plan ...
... Creontiades dilutus (green mirid) and C. pacificus (brown mirid) are major hemipteran pests of transgenic (Bt) cotton in Australia. Current integrated pest management (IPM) guidelines for mirids in Australian cotton, based on economic thresholds and sampling recommendations, were developed and disseminated to industry at the start of the 2005–06 growing season and have remained largely unchanged s ...
... Whole-plant cage field experiments were conducted in 2014, 2015, and 2016 to characterize cotton injury from a species complex of boll-feeding sucking bugs represented by the verde plant bug, Creontiades signatus (Distant) (Hemiptera: Miridae), brown stink bug, Euschistus servus (Say), green stink bug, Acrosternum hilare (Say), and redbanded stink bug, Piezodorus guildinii (Westwood) (Hemiptera: P ...
... Field experiments and supporting laboratory work were conducted to characterize the ability of the verde plant bug, Creontiades signatus (Distant), a boll-feeding sucking bug, to transmit a cotton seed and boll rot bacterial pathogen, Serratia marcescens (Bizio) (Enterobacteriales: Enterobacteriaceae). Serratia marcescens was originally isolated from bolls infested with verde plant bug in south Te ...
... Plant mapping has been included and evolving in cotton (Gossypium hirsutum L. [Malvales: Malvaceae]) research and management for over 100 years. Here we describe the structure and use of a plant mapping program (PMAPplus) that includes capabilities to record and manage insect injury to fruiting bodies by position and branch, compare it to existing programs (COTMAN and PMAP), and illustrate its use ...
... Geographic information system (GIS) tools were used to create pest monitoring maps based on field insect pest monitoring data taken during a two-year demonstration project in south Texas, 2015–2016. GPS-enabled handheld devices with GIS software were preloaded with a basemap and shapefiles containing insect abundance and plant injury data entry lines. Pest monitoring data were entered and stored o ...

Abstract:
... New data on thirty-four species of plant bugs (Insecta: Hemiptera: Heteroptera: Miridae) of French Guyana are provided. This number includes descriptions of two new species, Papaveronia matocqi sp. nov. and Urucuiana linnavuorii sp. nov., and thirty-two species cited for the first time from this country: Amapacylapus amapariensis Carvalho and Fontes, 1968; Calondas fasciatus Distant, 1884; Ceratoc ...
... The verde plant bug, Creontiades signatus Distant (Hemiptera: Miridae), has emerged as a threat to cotton in South Texas, causing boll damage similar to boll-feeding stink bugs (Hemiptera: Pentatomidae). Verde plant bugs were released into caged cotton for a one-week period to characterize the effects of insect density and bloom period of infestation on cotton damage and yield. When plants were in ...
... The ability to monitor verde plant bug, Creontiades signatus Distant (Hemiptera: Miridae), and the progression of cotton, Gossypium hirsutum L., boll responses to feeding and associated cotton boll rot provided opportunity to assess if single in-season measurements had value in evaluating at-harvest damage to bolls and if multiple in-season measurements enhanced their combined use. One in-season v ...

The ability to monitor verde plant bug, Creontiades signatus Distant (Hemiptera: Miridae), and the progression of cotton, Gossypium hirsutum L., boll responses to feeding and associated cotton boll rot development provided opportunity to assess if a single in-season measurement had value in evaluating subsequent at-harvest damage to bolls and if multiple in-season measurements enhanced their combi ...
... The verde plant bug, Creontiades signatus (Distant), has been present in south Texas for several years but has more recently been documented as an economic threat to cultivated cotton, (Gossypium hirsutum L. Our studies over 2 yr (2009 and 2010) and two locations (Weslaco and Corpus Christi, TX) investigated feeding-injury of the verde plant bug to a range of cotton boll age classes defined by bol ...
... Cotton yields have suffered losses from cotton boll rot during the last 10 to 15 years in areas of South Texas. Piercing-sucking insects feeding on cotton bolls, particularly stink bugs, have been implicated in introducing the bacterial disease. Along the Gulf Coast of South Texas, boll-feeding plant bugs occur, and may be associated with the disease. A replicated field survey was conducted in 201 ...
... Retention of cotton, Gossypium hirsutum L., bolls and squares (referred to as fruit retention), boll damage, and resulting lint and seed weight loss were assessed when two (2010) and three (2011) age classes of sympodial fruiting branches with different ages of squares and bolls where exposed to verde plant bug, Creontiades signatus Distant (Hemiptera: Miridae), in cages in the field. An increasin ...

... The actual feeding injury of Creontiades signatus Distant (Heteroptera: Miridae) was compared with a simulated technique during 2005, 2006 and 2008 by injecting varying dilutions of pectinase into cotton bolls at different boll sizes (ages) and into 2 or 4 locules to determine if such a technique could be used to reduce the time and labor involved with conducting economic injury level studies in t ...
... Studies were conducted to determine the most consistent and efficient method for rearing Creontiades signatus based on the number of ova, nymphs and adults produced on green bean pods and cowpeas. For pod rearing, 2 litre cartons with 12 openings on side walls were used. The openings were covered with a piece of cloth glued to the inside of the container. Small slits were cut in the cloth that all ...
... We investigated the oviposition behavior of Creontiades signatus Distant (Hemiptera: Miridae), a relatively new plant bug pest of south Texas cotton, Gossypium hirsutum L, on okra-leaf and normal-leaf genotypes that differed significantly in their leaf morphology and trichome densities. In a no-choice study, the site preference and numbers of eggs oviposited by C. signatus were identical for the o ...
... Research was conducted to evaluate the possibility that a plant bug damaging cotton, Gossypium hirsutum L., in south Texas is actually green mirid, Creontiades dilutus Ståål, which is the primary plant bug pest of cotton in Australia. Molecular comparisons targeting a fragment of the CO1 region of mitochondrial DNA were made on Creontiades specimens collected from the Lower Rio Grande Valley of Te ...
... Creontiades spp. (Hemiptera: Miridae) are sucking pests that attack buds, flowers and young pods in mungbeans, Vigna radiata (L.), causing these structures subsequently to abort. If left uncontrolled, mirids can cause 25-50% yield loss. Traditional industry practice has involved prophylactic applications of dimethoate to control mirids at budding and again a week later. The present trial was initi ...
